摘　　要：循环硫化床(CFB)锅炉添加石灰石进行脱硫,增加了炉内物料浓度和循环量,会对锅炉运行产生较大的影响。对1台CFB锅炉加石灰石后对物料循环、蒸汽参数、灰渣排放、受热面积灰等产生的问题进行了分析,提出了应对措施。Adding lime - stone in the process of desulfuration to increase concentration of materials in the furnace, and circulating materials amount, can more greatly affect the operation of circulating fluidized bed （CFB） boiler. The problems occurred after adding lime- stone into one CFB boiler have been analysed, and countermeasures for solving said problems being put forward.
